A PTFE Coated Butterfly Valve has a layer of PTFE (Polytetrafluoroethylene), FEP (Fluorinated Ethylene Propylene), or PFA (Perfluoroalkoxy) coating that makes it highly resistant to chemicals. The protective lining protects the valve from corrosion, wear, and damage by aggressive chemicals and is suitable for handling highly corrosive fluids in chemical processing, pharmaceutical, and food processing industries. The valve provides secure sealing and high durability and can ensure efficient fluid control even under extreme conditions.

The PTFE lining protects against harsh chemicals, making the valve ideal for corrosive applications.
The low-friction PTFE surface ensures easy, efficient valve movement with minimal wear.
Performs reliably in extreme temperatures, both hot and cold, without deformation or damage.
Requires minimal upkeep due to its durable, self-lubricating PTFE lining, reducing downtime and costs.
These valves are commonly used in industries such as chemical processing, pharmaceuticals, and water treatment, where corrosion resistance and non-contaminating flow are crucial for safe and efficient operations.
PTFE lining provides excellent chemical resistance, non-stick properties, and durability, making it ideal for handling corrosive or reactive fluids in demanding industrial applications.
Regular inspections for wear, alignment checks, and routine cleaning to prevent residue buildup are essential. PTFE’s non-stick properties help minimize the need for frequent maintenance.
Yes, they typically operate efficiently up to 200°C, depending on design, making them suitable for a wide range of thermal and chemical process environments.
A PTFE lined butterfly valve is a flow control device featuring a disc that rotates and a PTFE lining that resists corrosion in aggressive chemical environments.
